Windows Vista

I just got my Windows Vista upgrade in the mail today and decided to sit down tonight and install it. The first thing they suggest is that you make recovery CDs so you can go back to XP if you want to. That doesn't sound very reassuring to me. If Vista is so great, why would I want to go back to XP? Then I went to the PC Tools to make the CDs and learned that I would need 18 (yes eighteen) to create the backup. I only need 3 DVDs but of course I didn't have any DVDs, so I'm going to get some and do the recovery disks before I try out Vista.
